Described hereafter is a device for the conversion of electromagnetic momentum into mechanical momentum to be used in airless environment. The device is built from rotating disk, made of non-magnetic material, on the circumference of which plurality of bar magnets are mounted. The bar magnets are in a plane which is perpendicular to the plane of the disk and in a plane, which is perpendicular to the radius of the disk that meets the centre of the bar magnet. The disk is driven by a motor that causes it to rotate. The magnets are positioned in an angle relative to the rotation axis of the disk. When the disk rotates, mechanical momentum, perpendicular to the plane of the rotating disk is generated. This momentum acts on the disk and causes it to move along the axis of rotation of the disk.

A transportation network for providing propellant in space can include optical mining vehicles that concentrate solar energy to spall captured asteroids, capture released volatiles, and store them in reservoirs as propellants. The network can also have orbital transfer vehicles that use solar thermal rocket modules that focus solar energy on heat exchangers to force propellant through nozzles, as well as separable aeromaneuvering tanker modules with reusable heatshields and storage tanks. The network can have propellant depots positioned between Earth and a transport destination. The depots can mechanically couple to accept propellant delivery and to supply it to visiting space vehicles.

A magnetic field propulsion unit includes a magnetic field generating device with multiple conductive lines conduct a current to generate a magnetic field; a contact breaker arrangement individually transitions each of the multiple conductive lines from a conductive state to a non-conductive state; an energy supply unit provides the magnetic field generating device with electrical energy; and a control unit controls the energy supply unit so that energy supply to each individual conductive line is controlled and control the contact breaker arrangement. The multiple conductive lines are arranged along a longitudinal axis. The control unit supplies a first conductive line with electrical energy so that a first magnetic field surrounding the first conductive line is generated, transitions the first conductive line to a non-conductive state, and supplies a second conductive line with electrical energy so that a second magnetic field is generated.

There is disclosed a vehicle and a method for propelling the vehicle comprising a propulsion arrangement. The propulsion arrangement includes a chamber arrangement that is configured to store antimatter therein by using magnetic and/or electrostatic fields. The chamber arrangement and a centre of gravity of the vehicle are positioned at a relative distance from each other to form a matter-antimatter dipole when in operation. The matter-antimatter dipole provides a propulsion force to the vehicle. Optionally, the vehicle is a space vehicle (namely a spacecraft, a satellite or similar).

A filtering apparatus with a Body Force Generating Apparatus (BFGA) facilitates diffusion of objects of interest from a first reservoir to a second reservoir. The BFGA applies a body force per unit mass on objects of interest, such as air molecules, water molecules, dust particles, ions, electrons, and other types of elementary particles or constituent parts within a medium. The force field generated by the BFGA gives rise to a spatially varying potential field having a spatial or temporal gradient that is sufficiently strong at at least one location in space or instant in time such that objects of interest experience a departure from normal statistical behavior within that field. This can be employed to increase the pressure of objects of interest in a second reservoir relative to a first reservoir. A pressure modification apparatus and method can convert thermal energy into useful energy, such as mechanical work or electricity.
